Howdy all. I have a 1989 Yamaha xv250. Virago. She starts fine and runs strong g for about 10 min. Then just dies. It will start back up sometimes. It had a bad tank. Rust and messed up liner. I had the tank cleaned out and re sealed. Cleaned out the carb. But still does it. I bypasses the vaccume fuel pump. Works fine this way. The last time she died when I tried to start her j had no power for about 5 min. No lights no horn nothing. Then everything just came back. I'm thinking electrical. But don't know where to start short of systematically replacing wires one by one. Or if anyone has any ideas on what the problem could be. Please help.
